Taking ownership

Pipelines are executed as a user, who owns a schedule. This influences what
projects and other resources the pipeline has access to. If a user does not own
a pipeline, you can take ownership by clicking the Take ownership button.
The next time a pipeline is scheduled, your credentials will be used.

Note:
When the owner of the schedule doesn't have the ability to create pipelines
anymore, due to e.g., being blocked or removed from the project, or lacking
the permission to run on protected branches or tags. When this happened, the
schedule is deactivated. Another user can take ownership and activate it, so
the schedule can be run again.

Advanced admin configuration

The pipelines won't be executed precisely, because schedules are handled by
Sidekiq, which runs according to its interval. For example, if you set a
schedule to create a pipeline every minute (* * * * *) and the Sidekiq worker
runs on 00:00 and 12:00 every day (0 */12 * * *), only 2 pipelines will be
created per day. To change the Sidekiq worker's frequency, you have to edit the
pipeline_schedule_worker_cron value in your gitlab.rb and restart GitLab.
For GitLab.com, you can check the dedicated settings page. If you
don't have admin access to the server, ask your administrator.
